Other mistake: This is about the collector's edition DVD cover. On the back cover, the blurb says "With the help of young orphans Judy." But the cover doesn't make any mention of her brother. It should say "young orphans Judy and Peter" or "young orphan Judy."
Other mistake: Alan's dice rolls throughout the movie does not add up to the 33 steps needed to win the game. The four paths vary from 32-35 steps to win. Alan rolls a 5, Then his next roll isn't visible but the location of the elephant, when Robin Williams returns after being hunted by Van Pelt, is square 9, making his roll a 4 (the dice shows 3 but they aren't reliable since they could've shifted in the commotion). His next roll is a 7 and the winning roll is a 3 for a total of 19. Even if we allow his second (questionable) roll to score 11 it still only lands him on 26. Alan never rolls a bonus roll. And no, shortcuts across the board weren't used since Alan's elephant finishes its original path when it crosses into Jumanji. Furthermore, statements made by the cast that they only need a certain roll to win the game are pretty much all inaccurate if you count their rolls and steps along their path.
